Spin Fluctuation Theory of Itinerant Electron Magnetism (Springer Tracts in Modern Physics Book 253)

"This volume shows how collective magnetic excitations determine most of the magnetic properties of itinerant electron magnets. Previous theories were mainly restricted to the Curie-Weiss law temperature dependence of magnetic susceptibilities. Based on the spin amplitude conservation idea including the zero-point fluctuation amplitude, this book shows that the entire temperature and magnetic field dependence of magnetization curves, even in the ground state, is determined by the effect of spin fluctuations. It also shows that the theoretical consequences are largely in agreement with many experimental observations. The readers will therefore gain a new comprehensive perspective of their unified understanding of itinerant electron magnetism."--Publisher's website Front Matter....Pages i-xi Introduction....Pages 1-19 Fluctuations and Magnetism....Pages 21-48 Effects of Spin Fluctuations on Magnetic Properties....Pages 49-78 Magnetic Properties in the Ordered Phase....Pages 79-97 Thermal Properties of Itinerant Magnets....Pages 99-130 Magneto Volume Effect....Pages 131-177 Back Matter....Pages 179-181
